Hi,
this is my first post here!
I own a QNAP TS-451+ with RAM 2gb
firmware version: QTS 5.2.4.3105
CPU: Intel(R) Celeron(R) CPU J1900, fino a 1900 MHz (4 core, 4 thread)
I wish to improve RAM…
As I read in previous Qnap forum I must buy:
Actually I’m oriented in Kingston memory because “i knew” that Kingston is the best… but I know nothing (or a bot more) so I’m here to follow suggestion from who knows more than me…
Hi,
wrong RAM
The TS-451+ has only DDR3 RAM
DDR3L, SO DIMM, 204 Pin
I’ve understood nothing… sigh…
Really thanks to you 
I believe you want 2 of these.:OEMPCWorld.com: Kingston 4GB DDR3-1600 KFYHV1-HYC SODIMM PC3-12800 NON-ECC
But I would consider using your old NAS as a backup for a new NAS. You are EOL and at this point adding ram might not get you to the level you want.
maybe also increase to 16gb…is it possible?
NAS I has bought 2 years ago… sigh… I did not consider to change it 
That model MAX 8gb That is why I suggest new NAS.
Just thought I note here - in case anyone came across it - that I put 2x8GB sticks (so 16GB RAM in total) into my TS-451+ and it detected them accurately and does appear to be utilising them.
They were listed on EBay as “Crucial DDR3L 16GB 8GB 1600Mhz 2Rx8 PC3L-12800 1.35V SODIMM Memory Laptop 204pin”.
